thanks for the advice ray... this is easily 10 years old. and while this is off the wall it will get a new internal fan and transformer temp sensor (that failed 2 years ago).
i will look at the ac board relays when it is open too. todd On Monday, October 28, 2019 5:12pm, "Ray" <r...@solarray.com> said: You probably already checked this, but have you made sure the transfer switch wasn't switched to bypass? Also, you didn't mention the age of the system. I've seen quite a few Outbacks requiring rebuilds at 9+ years. Usually the control board, but the relays on the AC board can get cooked, if there are too many loads on backup, and of course the FET boards can go too. I started changing all the boards and the fan too, as I've had to come back 6 months later to replace a different board or fan. Reminds me of rebuilt carburetors....
